Compared to the Switch I feel like the Amp is all around more neutral. For me the Amp would just like to flip into a line and hold until late in the flight. The Switch has more turn and fade for it's speed. I only have one Switch, but it flies different from my Amps. MVP/Axiom's only real overlap so far imo is the Servo/Crave...All of the other discs are quite different even if they have similar stability ranges.
